Hummer service near Gaithersburg, MD

Superior has been my garage for over a decade based on a recommendation from another satisfied customer. Rob & Bob do a good job listening to the work I want done, describing the work they identify that needs to be done, and then completing the work on time. I recommend them to all my friends.

My car was making a rattling noise when I started it. They did an oil change and said that fixed the issue. Two days later it started doing it again. The shop is always too busy to diagnose and fix problems.If it’s not a basic or straight forward issue they can’t handle it.

Charges me $50 to clean corrosion off of my battery.

Paid $222 for A/C service and cabin air filter replacement because the air vent smells bad when I turn on the A/C. It still smells bad after 1 week of service.
